Abstract

Dynamic resistances appear in superconductors carrying dc currents subjected to ac magnetic fields. In coated conductors, multifilament structure is considered effective in reducing the dynamic resistance. However, in practical use, the coated conductors are plated with copper for improvement of stability and protection, so that coupling currents are induced under ac magnetic fields and deteriorate the effect of multifilamentation. The Spiral Copper-plated Coated-conductor cable (SCSC cable), which we developed to reduce as losses, might be effective to solve the problem. We conducted electromagnetic field analyses of four different copper-plated coated conductors to prove the effect; straight monofilament, straight multifilament, spiral monofilament, and straight multifilament coated conductors. We show the region where dynamic loss is generated (dynamic region) and then, discuss the difference of dynamic loss and hysteresis loss among the coated conductors. Also, the dynamic resistances in the analyzed coated conductors are compared.
